OFF
Ends the continuous measurement mode, and sets the sensor to
the idle state.
*RST:
OFF

See
Chapter 9.3, "Performing a buffered continuous average

Triggering
In a basic continuous measurement, the measurement is started immediately after the
initiate command, see also
Chapter 8.5.2.2, "Waiting for a trigger event"
However, sometimes you want that the measurement starts only if a specific condition
is fulfilled. For example, if a signal level is exceeded, or in certain time intervals. For
these cases, you can define a trigger for the measurement.

Trigger states
The power sensor has trigger states to define the exact start and stop time of a mea-
surement and the sequence of a measurement cycle. The following states are defined:
●
Idle
The power sensor performs no measurement. After powered on, the power sensor
is in the idle state.
●
Waiting for trigger
The power sensor waits for a trigger event that is defined by the trigger source.
When the trigger event occurs, the power sensor enters the measuring state.
●
Measuring
The power sensor is measuring data. It remains in this state during the measure-
ment. When the measurement is completed, it exits this state immediately.
8.5.2.2
Waiting for a trigger event
Before a trigger can be executed, the power sensor has to be set to the waiting for trig-
ger state. Depending on the required number of measurement cycles, you use one of
the following commands:
●
A new measurement cycle is started automatically after the previous one has been
terminated.
●
The number of measurement cycles is restricted.
If
1
is set, the command starts a single measurement cycle that
renders one result. Every time you send this command, a new measurement cycle
is started.
